LM1238
110 MHzI2C Compatible RGB Preamplifier with Internal
Simple OSD Generator and 4 DACs
General Description

The LM1238 pre-ampisan integrated, three channel video
pre-amp.It hasan I2C compatible interface which allows
controlofallthe parameters necessaryto directly setup and
adjust the gain and contrastin the CRT display. Four I2C
compatible DACs are availableto control monitor bias and
brightness circuits. The LM1238 preampis designedtobe
100% compatible with the LM246x high gain driver family
andthe LM2479/80 Clamp ICs.
Black level clampingofthe video signalis carriedout directly the AC coupled input signal into the high impedance
pre-amplifier inputs, eliminating the need for additional
clamp capacitors. Horizontal and vertical blankingof the
outputsis provided. Vertical blankingis optional andits
durationis register programmable.
Features
I2C compatible microcontroller interface Internal OSD generator with16 setsof color icons OSD override allows OSD messagestobe displayed
while blanking input video Internally generated burn-in screen4 DAC outputs (8-bit resolution)for bus controlled CRT
bias and brightness Spot killer which blanksthe video outputs when VCC
falls belowthe specified threshold Suitablefor use with discreteor integrated clamp, with
software configurable brightness mixerH andV blanking(V blankingis optional and has
register programmable width) Power Saving Mode with 65% power reduction Matchedto LM246x driver and 2479/80 clamp
Applications
Low end 15" and 17" bus controlled monitors with OSD 1024x768 displaysupto85Hz requiring OSD capability Very low cost systems with LM246x driver
